Are Glofish Genetically Engineered

GloFish, as they’re called, are fish that have been genetically modified by scientists into fancier, more colorful versions of themselves by using genes snatched from other organisms, such as sea anemones.

How are GloFish genetically modified?

GloFish (Figure 1) are a type of transgenic zebrafish (Danio rerio) that have been modified through the insertion of a green fluorescent protein (gfp) gene. … Rather, there are several gfp gene constructs, each encoding a different colored phenotype, from fluorescent yellow to fluorescent red.

How were GloFish developed?

Scientists created the GloFish by inserting fluorescent genes from jellyfish and sea anemones into the eggs of a silver and black zebra danio, a tropical fish from India. The fish was designed to help scientists determine when waterways were contaminated. If they glowed, it meant there were pollutants in the water.
